Abstract: PURPOSE: A method for analyzing a nitrite emitted from a cell by using a capillary electrophoresis is provided to reduce cost, time and labor for analyzing the reaction in a cell by using a capillary electrophoresis. CONSTITUTION: A method for analyzing a nitrite emitted from a cell by using a capillary electrophoresis comprises the steps of setting up a condition of a capillary electrophoresis, writing a concentration testing curve of a detecting peak versus a standard material by detecting a nitrite under the set condition, growing a cell on a medium, detecting a nitrite peak emitted from the cell by using a cell growing supernatant, and determining nitrite concentration by applying the nitrite peak to the concentration testing curve.

Abstract: PURPOSE: A determination method of protein phosphorylation reaction by enzyme activity is provided, thereby easily and rapidly analyzing the protein phosphorylation reaction. CONSTITUTION: A determination method of protein phosphorylation reaction by enzyme activity comprises the steps of: determining the optimal pH and concentration of a buffer solution for phosphorylation reaction of myelin basic protein(MBP) by extracellular signal-regulated kinase(ERK); adding the optimal concentration of compound to the buffer solution in order to inhibit the adsorption of peptide to the inner wall of a capillary tube and increase the detection sensitivity; determining MBP peptide from the active region of MBP peptide by ERK, -PRTP- as a center for effectively carrying out the phosphorylation reaction by ERK under the same condition; detecting the phosphorylation reaction of MBP peptide by ERK using a capillary tube electrophoresis using the buffer solution; and additionally confirming the phosphorylation reaction detected using a matrix-supported laser removing/ionizing mass analyzer.
